ceph-post-file will upload files or directories to ceph.com for
later analysis by Ceph developers.

Each invocation uploads files or directories to a separate directory
with a unique tag. That tag can be passed to a developer or
referenced in a bug report (http://tracker.ceph.com/). Once the
upload completes, the directory is marked non-readable and
non-writeable to prevent access or modification by other users.

Basic measures are taken to make posted data be visible only to
developers with access to ceph.com infrastructure. However, users
should think twice and/or take appropriate precautions before
posting potentially sensitive data (for example, logs or data
directories that contain Ceph secrets).
